## What is Fuel Calculator?

Fuel Calc helps you calculate fuel economy, convert MPG and L/100 km, track fuel costs, and keep useful vehicle records in one place.

Use the calculator to work out fuel economy and journey cost from your fuel amount, distance, fuel price, and odometer reading. Use the converter when you just need a quick MPG to L/100 km conversion, or the reverse.

Saved calculations and conversions are kept in History so you can review past entries instead of starting from scratch each time. Charts make it easier to spot trends over time, compare saved values, and filter entries by date range.

Fuel Calc also includes service reminders for MOT, servicing, insurance, tax, oil, and custom vehicle tasks. Reminders can show when attention is needed, and you can choose how early the warning appears.

*2026-05-20, version 2.1.2*

Very easy to use and very helpful

### 3/5 — Some small improvements could make this perfect

*2026-02-15*

Please make it possible to set a default view and save settings. For example I always want miles not km but km is always the default! White on mint green can be hard on the eyes. Making it possible to select Calculator as default screen along with the other improvements would make this a 10/10 app!!
